i've recently bought a new PC with Intel's P67 on board (MSI P67A-G45 B3) and i have a problem with installing an USB TV Tunner WinFast DTV200H. I've tried to install this device on many diffreny (8 exactly) machines including two with P67 chipset (mentioned earlier MSI P67A-G45 B3 - with newset BIOS installed - and ASUS P8P67 B3 mainboards). The problem occurs only on those two computers. System can't recognize tunner and in Device Manager it is showed as "Unknown Device". I've also tried to plug it after installing corresponding driver and to install this driver manually from Device Manager, but the problem still persists. Both computers have Windows 7 64bit system installed. Can I ask for some advice?

Thanks for answer. This is an USB device, i've upgraded BIOS to the latest version available. Before BIOS update my computer couldn't pass the boot sequnce making continous sequence of short beeps. After BIOS update, this problem has been resolved, but i still can't install the device. I've also wrote to LeadTek and they answered that they haven't met this problem before.

Considering the issue description and the troubleshooting you have performed, we can only conclude that this is compatibility problem with the chipset itself. We can recommend testing other devices on the ports, to ensure they are working fine.

Intel will stand behind its products but we cannot guarantee compatibility with any and every other product available on the market. We build our products to industry standards but there is still the possibility of incompatibility.

I've tested many other USB devices from printer to mobile phone and only this one is not working right. I'm going to wait now for any new drivers or bios update or any new message from LeadTek. I just wondert why this problem did not exist in previous models of Intel chipsets.
